The X Factor’s spectacular Live Shows continue tonight with the finalists once again lining up to perform in front of the live studio audience and millions of viewers at home.

This week the finalists will be celebrating the best of The X Factor with The X Factors 10th Birthday Party, from the most memorable performances on the show, to hit singles released by past contestants.

There will also be a special performance from platinum selling artist and X Factors’ very own heartthrob Olly Murs.

The remaining contestants will battle it out to win over the public and this week the two contestants who poll the lowest in the viewers’ vote will face the dreaded sing-off on Sunday night.

Ever popular Dermot O'Leary presides over proceedings while judges and mentors Louis Walsh, Sharon Osbourne, Gary Barlow and Nicole Scherzinger take their seats behind the judges’ desk to battle it out with their contestants. Louis has the Boys, Sharon the Overs, Gary the Groups and Nicole the Girls.
